For each interface, both an IPv4 and an IPv6 address can be configured. It is possible for both addresses to be active at the same time. It is also possible to only configure one of the addresses and leave the other field empty, in which case the '''ERSPAN''' mode will only apply to the configured address. If the IPv4 address is configured, the interface will respond to ARP requests for the IPv4 address. If the IPv6 address is configured, the interface will respond to Neighbor Solicitation messages for the IPv6 address. | |||
Once the '''ERSPAN''' mode is activated, the ERSPAN interface responds to '''ICMP/ICMPv6 Ping''' messages. Once ERSPAN is configured, you should be able to send a ping to the IP address(es). | |||
